MULTIPLE MAGAZINE FOR TYPGGRAPHIC MACHINES.

Specification of Letters Patent. Patented BT31. 21 1922.

Original application filed March 15, 1918, Serial No. 222,750. Divided and this application filed July 21, 1920. Serial No. 897,883.

To all whom it may concern:

Be it known that I, FREDERICK W. LETSOI-I, a citizen of the United States, and residing atBaltimore city, Maryland, have invented certain new and useful" Improvements in Multiple Magazines for Typographic Machines, of which the following is a specification.

This invention relates to a multiple magazine for typographic machines and particularly machines of the kind described in my copending application, Serial No. 222,760, filed March 15, 1918-, of which the present application is a division.

It is the object of the invention to provide a multiple magazine which can be employed with a typographic machine having a sin gle distributor and a single assembling mechanism, and which can be easily and quickly adjusted so as to bring any desired section of the magazine into cooperative relation with the distributor and assembling mechanism. A further object of the invention is to provide a construction which can be so positioned that the various sections of the magazine can be easily withdrawn therefrom and other sections substituted. A still further object is to provide a 1nechanism of the kind referred to which simple in constructionand operation and which can be easily manipulated, to place the same in any desired position.

.The invention is set forth in the following specification and illustrated in the accompanying drawings in which:

Figure 1 is a front view of the upper portion of a typographic machine showing the invention applied thereto;

Figure 2 is a side elevation of the construction appearing in Figure 1;

Figure 3 is a side elevation of the mutiple magazine involving the present 1 invention showing certain details of construction and also the relation of themagazine to other parts of the machine;

Figure 4 is a detailed view illustrating the matrix escape pawls used in each section of. the multiple magazine.

Referring to the drawings in detail, represents the framework of a typographic machine to which the multiple magazine of the present inventiou'is applied.

The distributing mechanism of the machine is generally designated by the numeral 11 from which the matrices are dropped into the chutes 12 which serve to conduct them into themagazine. Other chutes 13 are pro V'lClGCl for conducting the matrices from the magazine to the assembling mechanism. It willbe understood that when any particular section of the multiple magazine has its lower end adjusted to register with the as sembler chutes 13, its upper end will register with the chutes 12 of the distributing mechanism.

The multiple magazine of the present invention comprises a frame which consists of three parts l t, 15 and 16, suitably secured together in oii'set or stepped relation and in which three magazine sections 17, 18am]. 19 are removably mounted. Each of the magazine sections is supported at its front and rear ends and the rear end of each magazine has connected with it a transverse bar 13 which is adapted to engage between suitable bars 13 secured to the various parts of the frame. The magazine frame is provided with trunnions 20 which are rigidly secured to one 03!? the parts thereof, these trunnious being arranged near the center of: gravity of the frame. These trunnions carry rollers 21 which are adapted to run on tracks 22secured to the framework of the nmchine. The lower section let of the magazine frame carries at the rear a bracket 23 in which a wheel 24; is rotatably mounted, this wheel being adapted to enter a recess or socket 25 in a bracket 26 secured to the frame of the machine. The uppersection 01 the frame near its front end is provided with a handle 27 by which the magazine frame may be moved to various positions. ltach part of the magazine frame is provided on each side with pins 28 which are adapted to engage with suitablenotches provided in brackets 29 secured to the framework of the machine, this arrangement constituting means for holding the magazine frame in various positions. Means are also provided for locking the magazine frame in difi'erent positions, such means comprising a spring bolt 30 mounted in the trame'work oi the machine and positioned to engage holes 31 inthe variou parts ot the magazine frame Each oi the magazine sections is provided at its lower port-ion with suitable matrix release pawls 32 which are operated by push rods connected to the keys (not shown} constituting the keyboard of the machine, it being understood that these parts are the same or analogous to those generally employed in machines of this char acter.

Briefly referring to the operation of the mechanism it will be understood that the parts are so proportioned that the magazine sections and the parts of the frame are slightly heavier in the rear of the trunnions 20 than in front so that the frame when not locked in operative position has a tendency to rotate upon said trunnions until the wheel 24; rests in the socket 25 of the bracket 26. lVhen it is desired to change the position of the magazine so that. a a different section may be brought into register with the distributor and assembler chutes the bolt is withdrawn and by means of the handle 27 the entire magazine may be rotated about the trunnions 20 and can be moved along the trackway 22 of therollers 21. Any section of the magazine can thus be brought into register with the distributing and assembllng mechanism. And when the magazine is thus unlocked it may be rotated about the trunnions 20 into a horizontal position with the wheel 24 resting in the socket 25 so that sections of the magazine may be removed from the frame by disengaging the bars of the magazine sections from the bars B secured to the various parts of the frame.

I The construction as awhole therefore can be easily manipulated to place different sections of the magazine in register with the other mechanism of the machine and also positioned so that removal and replacement of the magazine sections can be easily accomplished.

It is apparent that various modifications and details of construction may be emplo ed within the scope of the invention and without departing from the spirit thereof as embodied in the appended claims.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: i

1. In a typographic machine in combination, a plurality of magazines for receiving and holding matrices, an inlet chute and an outlet chuteffor directing matrices into and from the magazines, a frame upon which said magazines are removably supported, said frame including a plurality of sections arranged in stepped relation, one section for each of said magazines, a trunnion on each side of said frame, a wheel on each of said trunnions, a horizontal track on eae'h side of said frame, said frame being tiltable upon said trunnions and movable bodily along said tracks, whereby diiferent magazine sections are brought into register with said chutes, a pin on each of said frame sections near the front end thereof, a fixed member having a notch adapted to receive one of said pins to position and hold the frame as different magazines are presented to the chutes, and cooperating means on each of said sections and the machine frame for locking the magazine frame in different positions.

2. In a typographic, machine in combina} tion, a plurality of magazines for receiving and holding matrices, an inlet chute and an outlet chute for directing matrices into and from the magazines, a frame upon which said magazines are removably mounted, said frame including a plurality of sections arranged in stepped relation, one section for each of said magazines, a trunnion on each side of said frame, the portion of the frame in the rear of the trunnion being slightly heavier than the portion in front of the same, a wheel on each of saidtrunnions, a

horizontal track on each side of said frame,
